The Messenger of Allah ﷺ said, "He whose neighbor is not safe from his harm will not enter Paradise."
أن رسول الله ﷺ قال: لا يدخل الجنة من لا يأمن جاره بوائقه.
Muslim reported it in the Book of Faith (46) through several routes, from Ismail bin Jafar, from Ala, from his father, from Abu Hurairah, who mentioned it.
